Title: Moulding plastics reinforcement to filter element - forms internal ribs with non-collapsible mould core
IPC: B01D29/11
Filed: 1973-02-02
Abstract: Tubular filter element has a circumferential stiffening rib of plastics matl. moulded on the inside of a filter sheet, the rib following a continuous, helical path so that the mould core, which is made with a rib-forming helical groove, can be extracted from the filter element by a simple unscrewing motion. This permits the use of a simple, non-collapsible, retractable core instead of the more complicated, more expensive and more troublesome collapsible core previously employed to produce internal, circumferential, reinforcing ribs, generally required when filtration takes place by fluid passing radially inwards through the filter sheet.

Title: Dispersal of powdered solids in liquids - in a machine giving a constant ratio of liquids to solids
IPC: B01F5/24
Filed: 1973-11-14
Abstract: A device for dispersing a powdered solid into a liquid includes a funnel shaped channel whose walls are formed by films of the liquid and into which the powder is dispensed, so that it does not touch the walls of the vessel. The liquid and solid are mixed at this point in the ratio desired in the final product. The mixt. is conveyed to the inlet of a mechanical mixing device which exerts a slight suction at the inlet so that the liquid/solid mixt. is aerated as it enters the mixer. The device is used in the dispersion of thickeners, starch, and flour, proteins such as gelatine, albumen and dried milk in water, as well as the dispersion of all solids having a high solubility in the liquid in which they are to be dispersed. The device prevents clogging by damp conglomerations of solids and is simple and inexpensive.

Title: Separator for gas streams - respectively charged with particles and freed from particles by centrifugal force
IPC: B01D45/16
Filed: 1974-03-08
Abstract: A separator to separate gas streams charged with particles from streams freed from particles by centrifugal force consists of a curved duct, which may be a pipe or the volute of a centrifugal fan, and one or more deflectors fixed or movable placed at the outlet of the curved duct, in which the sepn. has been brought about by centrifugal force. The layers may be extracted in the same or in different ducts. The centrifugal fan may have one or two suction inlets and the volute may be divided into zones by partitions parallel to the plane of the rotor each zone having a movable deflector dividing the flow parallel to the axis of the fan to isolate a layer in which particles are concentrated. The deflector may be rotated so as to vary the flow areas of the streams to improve the separation. The curved duct may divide into two ducts with two deflectors in series, the second further purifying the stream from the first. The separator does not cause large press. drops and does not contain any complex components and uses less energy than existing separators.

The junction point is connected to the output of a circuit (4, R4) determining a voltage proportional to the current supplied by the battery and connected to a voltmeter responsive to the sum (V3) of the voltage at the junction point and of the proportional voltage.
Patent FR-2270972-A1 (FR)
Title: Heating pre-sintered metal powder compacts prior to forging - using high frequency induction heating in a protective atmos
IPC: B22F3/17
Filed: 1974-05-15
Abstract: Process for heating pre-sintered metal blanks intended for forging, the novelty being that the direct heating of the blank throughout its mass is achieved by electric current induced at high frequency, the induction coil surrounding, and being close to, the blank. The blanks are pref. heated to 1100-1300 degrees C using a current with frequency 12 megahertz. Immediately after heating the blank can be forged. In heating iron powders and pre-alloyed iron powders, a high temp. is attained which accelerates sintering and reduces the heating time required; the graphite present in the powder mixtures rapidly diffuses through the grains and as soon as the current is switched off the temp. of the blank equalises almost immediately and it can be directly forged. An inert gas, eg. Ar or N2 is used to prevent oxidn. of the blank.
Patent FR-2231548-A1 (FR)
Title: Automatic operation of vehicle trailer brakes - via a pneumatic distributor and servo-distributor on the towing vehicle
IPC: B60T13/38
Filed: 1974-05-30
Abstract: Between the distributor and the servo-distributor is fitted a reversible cut-off which connects the servo-distributor either with the open air or with the distributor and which has a control element which is operated by the pressure in the vehicle parking brake line acting against the vehicle spring parking brakes. Pressure from the parking brakes moves a piston-spool in the cut-off to in turn communicate the distributor and servo-distributor by pressing down a resilient valve rod connecting the two. A mass on the spool inertially damps its movement.
